Influences on the cycle time in RUN-Solo system state

RUN-Solo system state
In RUN-Solo system state, the primary CPU is in RUN operating state. The primary CPU
executes the cyclic, time- and interrupt-controlled program execution on its own. The backup
CPU is in STOP operating state, is switched off or defective.
Influence on the cycle time
In RUN-Solo system state, the primary CPU behaves exactly the same as a standard CPU
(non-redundant CPU) with regard to cycle time monitoring. Additional information on this is
available in section "Cycle time (Page 24)".
